Integrated circuits and devices revolutionized particle physics experiments, and have been essential in the recent discovery of the Higgs boson by the ATLAS and CMS experiments at the Large Hadron Collider at CERN [1,2]. Particles are accelerated and brought into collision at specific interaction points where detectors, giant cameras of about 40 m long by 20 m in diameter, take pictures of the collision...
The CMS detector's core is composed of the largest silicon detector ever built. This tracker consists of a hybrid pixel detector with 66 million channels and a 200 m silicon strip detector with 10 million read out channels. Thanks to its fine granularity, it can perform excellent tracks and vertices reconstruction, essential objects in physics analyses. However, the next LHC upgrades will expose CMS...
In December 2009 the ATLAS experiment at the CERN Large Hadron Collider (LHC) recorded the first proton-proton collisions at a center-of-mass energy of 900 GeV and this was followed by the unprecedented energy of 7 TeV in March 2010. The SemiConductor Tracker (SCT) is the key precision tracking device in ATLAS, made up from silicon microstrip detectors processed in the planar p-in-n technology. The...
We propose a new generation of VLSI processor for pattern recognition based on Associative Memory architecture, optimized for on-line track finding in high-energy physics experiments. We describe the architecture, the technology studies and the prototype design of a new R&D Associative Memory project: it maximizes the pattern density on ASICs, minimizes the power consumption and improves the functionality...
ATLAS is a multi purpose detector built to study proton-proton collisions, at center of mass energies up to 14 TeV, as provided by the Large Hadron Collider at CERN. ATLAS is equipped with an inner charged particle tracking system composed of silicon and drift tube based detectors. The required precision for the alignment of the most sensitive coordinates of the silicon sensors is at the level of...
The Large Hadron Collider (LHC) will go to through an increase of luminosity that will lead to Super LHC in 2016. The upgrade of the machine will increase the luminosity by a factor 10 providing an opportunity to explore new physics, but will make stringent demands to the LHC detectors. The tracking detectors of the ATLAS and CMS experiments will have to be replaced by more powerful devices. Some...
